This is interesting; I haven't seen a recent ksh manual.  Looks like ksh
can do "widgets" too, after a fashion.  Use of "trap" on a magic KEYBD
signal to invoke the function is kinda cutesy.

Wrong.  You can.  There might be better solutions than mine here.  This one
works in vi mode, and the next one in emacs.

function vi_tab
{
    # what looks like a space on the next line is a physical tab
    if [[ ${.sh.edmode} == "^[" && ${.sh.edchar} == "	" ]] then
        .sh.edchar="^[\\"
    elif [[ ${.sh.edmode} != "^[" && ${.sh.edchar} == "=" ]] then
        .sh.edchar="=a"
    fi
}

trap 'vi_tab' KEYBD

function emacs_tab
{
    # what looks like a space on the next line is a physical tab
    if [[ ${.sh.edchar} == "	" ]] then
        .sh.edchar="^[^["
    fi
}

I am surprised more people don't know about this.  It was one of the
first nifty things I learned in ksh93. :)  But what's the best is that
people make statements about things which they know nothing about.
Like that it cannot be done, even though they don't use ksh93.  I love
that.
